Advice 1: How do you know that burned motherboard

Any computer equipment can break. Fortunately, in case of breakage of any component of the PC do not need to buy a new computer. Enough to figure out what has failed, and replace this equipment. Usually if a component fails, it can be determined according to several criteria. The hardest to determine if it will burn the motherboard, then the computer may not start. If the PC does not start all the time or is rebooted, you first need to check the motherboard.
How do you know that burned motherboard
You will need
  • Computer, motherboard, screwdriver
Instruction
1
If the computer does not start, the first thing you need to eliminate the possibility of breakage of other components. This will help to determine the serviceability of the motherboard.
2
You start the computer. First, it works to load. But as soon as it comes to operating system starts, the screen goes black and then nothing happens. So, out of order hard drive or video card. With the motherboard then all is fine.
3
Open the cover of the system unit. Pull out the motherboard, all memory modules. Turn on the computer. To hear the squeak of the speaker. If no, there's no sound and the motherboard does not react to the lack of memory modules, so it is out of order.
4
Pay attention to the capacitors on the motherboard. If they are slightly swollen, then, the Board is really burned. Bloating of capacitors can be caused by unstable operation of the power supply of the computer. The failure of the capacitors does not mean that the motherboard needs to be changed. To replace the capacitors can be at home, if you have experience soldering, or in the service center.
5
On some models of motherboards in case of failure of CPU when the computer is turned on can occur warning Install correct central core. Turn on the computer, if the system starts to boot and appears in the window this inscription, then, the motherboard is not burned, but broken CPU. In this case you need to replace the processor.
6
One of the surest ways to test the motherboard is. Unplug from the motherboard to the memory modules, graphics card, hard disk and all other devices. Leave only the CPU. Turn on the computer. If after it starts you hear the bell, so motherboard is OK. In this case, it broke one of the disconnected devices.

Advice 2 : How to define, what burned down the maternal

How would the quality nor was the equipment from breakages nobody is insured even when there is a guarantee from the manufacturer. The motherboard is the most important constituent element of the computer system unit. If you find it faulty, because of certain characteristic signs, you will be able to determine whether burned out the motherboard or cause the failure of another part.

If you turn the computer on it fails to boot, but the fans are spinning on the Board, check the chip on the motherboard overheating. Remove the system cover and use your finger to touch these circuits. If they become very hot and burn your finger, most likely that is what caused the failure of the motherboard.

At the time of turning on the computer listen to all the sounds emanating from him. If the machine is turned off immediately after the start and then not turn on and you hear clicking or crackling is a sign of a short circuit on the motherboard. One of the reasons for such a failure in contact of the conductive element you are interested in details with the system unit.
3
Also on the fault of the motherboard can specify the complete absence of any sounds when the computer starts. If you hear a single signal, but does not turn on the monitor, check the connection to the video card and connect the video card connector on the motherboard. Then remove the memory card from the slot and place it back in place. If the situation does not change after you start the computer, the motherboard should be changed.
4
There are times when the computer will not turn on or off under heavy load, such as when you run "heavy" games. This is one of the indicators of a fault in the CPU power circuit on the motherboard or failure of the current that is applied to it. To confirm or refute these versions remove the motherboard from the system unit. If you see the darkened area, the reason lies in the prolonged overheating of the transistors on the Board. You can replace them, but there is no guarantee that the other elements will work properly. Often all these signs indicate that the motherboard is burned.
